Specification of Letters Patent.

ratented July 17', 1906r Application lecl April 8, 1905. Serial No.254.618.

1'0 ttt w/torn/ it mfcty concern:

Be it known that I, DOMINIK IVE, a resident of Solingen, Germany,Brhlerstrasse 74, have invented a certain new and useful Improvement inMeans for Fastening the wedges driven in from the front, as hithertoApracticed., is obviated.

Referring to the drawings which form a part of this specification,Figure l is a front end elevation. Fig. 2 is a side elevation; and Fig.3 is a plan of the head of a tail or tilt hammer, showing only part ofthe hammershaft.

a is the hammer-head having upper converging walls, and b is the woodenshaft.

c is a wood block with inclined sides.

d is a metal ring of rectangular shape in plan, having its insidesurfaces shaped to iit the-upper part of the head a.

e e are two metal wedges.

f is an ordinary bearingwedge.

In fastening the hammer-head L on the handle b according to thisinvention the metal ring d is slipped on the hammer-head and the woodblock c is placed with its wider base resting on the shaft b insidethehammerhead. Then the wedges e e are inserted, one on each side,between the block c and the hammer-head and then driven iirmly downwardin a direction approximately parallel to the working plane of the hammertoward the shaft b. By this means the hammer-head is fixed firmly on theshaft and in such a manner that it will have a constant tendency tobecome fixed more tightly on the shaft by the impact of the hammer.Further, this fastening will prevent the splitting of the hammer-shaft.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

In combination in a hammer-head having an opening therein extending froma point near its lower end through the top the upper walls of said headbeing convergent, a handle fitting in said opening, a wedge-shaped blockresting on said handle within theopening metal wedges adapted to bedriven on each side of the block in a direction approximately parallelto the movement ofthe handle between said block and the hammer-head, anda ring surrounding the upper part of the hammer-head, substantially asdescribed.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

l DOMINIK IVE.
